METHOD FOR ENTIRE REMOVAL OF SPACE TRUSS AND ASSISTIVE SUPPORT MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/120687
Kind Code:
A1
Abstract:
A method for the entire removal of a space truss, and an assistive support mechanism therefor. The assistive support mechanism is provided on a vertical support rod (11) of a truss structure (1), and comprises an assistive support assembly (2) and a lifting assembly (3). The assistive support assembly (2) comprises a support platform (21), a lattice support member (22) provided on the support platform (21), and a conversion platform (23) provided at the top of the lattice support member (22). The lifting assembly (3) is provided at the top of the conversion platform (23), and comprises a stranded wire (31) for fixing the truss structure (1), a lifting member (32) for driving the stranded wire (31) to move up and down, and a control member for controlling the lifting member (32). The method for the entire removal of a space truss comprises: providing an assistive support mechanism directly on an existing vertical support mechanism, performing primary removal of a truss structure (1) in the sky, separating the truss structure (1) from a vertical support rod (11), using a lifting member (32) so as to lower the truss structure (1) stably to the ground, and then performing secondary removal of the entire truss, such that the main removal work is done on the ground, thereby reducing the need to remove assistive means, and operational risks, and improving working efficiency.
